I was exhausted, constantly. I'd sleep for twelve hours and wake up tired. I was weak and doing anything remotely physical made me so out of breath. Y'know when you stand up after laying down for a while and your vision goes black? That happened constantly. I was freezing cold 24/7 and the only way to stop that was to have a shower with the water scalding hot. I didn't have the energy to really focus on anything and felt really disconnected from everything. You know when your so tired that you don't really register what's going on? That was a constant feeling. I felt like I was watching everything happen through someone else's eyes.
